Sleep quality in COVID-19 recovered patients

Area of Science:

• Medical Research
• Public Health
• Sleep Medicine

Background:

• Coronavirus disease 2019 (COVID-19) presents significant health challenges.
• Limited data exists on the long-term health sequelae for COVID-19 survivors.
• Sleep disorders are a common but often overlooked post-illness complication.

Purpose of the Study:

• To investigate the prevalence and extent of sleep disorders in individuals who have recovered from COVID-19.
• To compare sleep quality between COVID-19 recovered patients and a control group.
• To identify specific sleep parameters affected by prior COVID-19 infection.

Main Methods:

• A case-control study involving 256 COVID-19 recovered patients and 491 controls.
• Participants were adults aged 18 years and above.
• Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), with calculations for sleep latency and required sleep hours.

Main Results:

• 84% of recovered patients reported poor sleep quality compared to 78% in the control group (p=0.014).
• Recovered patients required more average sleep hours (6.899±3.7869) than controls (6.44±1.477) (p=0.01).
• Sleep latency did not significantly differ between groups (p=0.374).

Conclusions:

• Sleep disorders are significantly more prevalent in patients who have recovered from COVID-19.
• COVID-19 recovery is associated with impaired sleep quality and increased sleep duration needs.
• Further research is warranted to understand the mechanisms and long-term implications of post-COVID-19 sleep disturbances.
